Colorectal surgery is the broad term for surgical procedures performed on the colon, the rectum and the anus. There are various different surgical procedures which fall under colorectal surgery and these are used to treat a vast array of disorders, such as:
- Anal cancer
- Colorectal cancer
- Severe complications related to constipation
- Anal injuries
- Inflammatory conditions of the gastrointestinal tract
- Congenital defects
- Procedures: The surgeries under colorectal surgery are performed after diagnostic tests such as proctoscopy, sigmoidoscopy and defecating proctography. The most common diagnostic test is colonoscopy. These help to identify the origin and nature of the problem and decide which surgical procedure is to be followed. The procedures under colorectal surgery are as follows:
- Colectomy: This procedure involves removal of a section of the large intestine. This is known as partial colectomy. In extreme cases, such as advanced cancer or severe gastrointestinal infection, the entire colon is removed and this is called total colectomy. Sometimes, the rectum is also taken out along with the colon and this is called proctocolectomy.
- Colonic polypectomy: An abnormal growth of tissues in the inner lining of an organ is known as a polyp. Colonic polypectomy is done to eliminate polyps from the colon and rectum before they become malignant. This can be done endoscopically. Surgery is required in case of large polyps.
- Strictureplasty: Chronic or repeated bowel inflammation causes scar tissue to accumulate in the large intestine. This results in the narrowing of the colon. Stricturoplasty removes the scar tissue so that proper flow of digestive contents is resumed.
- Colostomy or Ileostomy: A damaged section of the colon is removed and the shortened intestine is then attached to another opening (stoma) in the anterior wall of the abdomen.
- Hemorrhoidectomy: This surgical process is used for swollen hemorrhoids or blood vessels, which form in the anal canal. Hemorrhoidectomy is extremely effective in removing hemorrhoids, but the surgery also involves a number of complications.
- Anoplasty: Anoplasty or imperforate anus correction is done to correct birth defects in the rectum and the anus. The structural flaw does not allow the stool to pass properly from the rectum and so it is repaired through surgery. If you wish to discuss about any specific problem, you can consult a General Surgeon.
An umbilical or belly button hernia occurs when a part of the intestines or the abdominal lining protrudes through an opening in the abdominal muscles. The protruding intestines may get squeezed or strangulated resulting in the blood supply getting cut off. Surgery may be required in serious cases of umbilical hernia. Doctors often suggest a special diet for umbilical hernia patients as this helps to prevent further complications.
Foods to avoid
Certain foods are not recommended for people with an umbilical hernia and should be avoided.
White refined flour foods made from white refined flour have a low fiber content. Eating these foods may cause constipation and should therefore be avoided. This is because constipation causes straining of the abdominal muscles during bowel movements and may cause further protrusion of the intestines through the abdominal muscles in the region of the belly button.
Low fiber fruits and vegetables the low fiber content in these foods can also lead to constipation. Examples of fruits and vegetables with low fiber content include skinless raw fruits, cooked fruits, and canned or cooked vegetables without seeds, hulls or skin.
Fatty foods foods with a high fat content should be avoided. This is because obesity results in greater pressure on the abdominal muscles and can increase the risk of umbilical hernia. Examples of foods with a high fat content include fatty meat such as pork, whole milk, butter, cream, margarine and fried foods.
Sugar limit your calorie intake by cutting down on foods such as pastries, cakes, chocolates and soda pop. Limiting your sugar intake will also help you to lose some weight, taking pressure off your abdominal region.
Foods to include
A special diet is required after umbilical hernia surgery. This will help you to minimize your convalescence time. The special dietary requirements include:
Fruits fresh fruits that have high fiber content and are rich in antioxidants should form a part of every meal. The high fiber content will ensure that you do not get constipated and the antioxidants will help protect your body and boost your immune system. Try to eat different types of fruits so as to get adequate amounts of different vitamins. Citrus fruits, berries, and apples are some examples of fruits with a high fiber and vitamin content.
Vegetables these too have a high fiber content that will guard against the dangers of constipation after an umbilical hernia surgery. They also have high levels of vitamins and minerals and should also be included with every meal.
Lean meat meat is a source of protein, which is essential to the repair of damaged tissue. Lean meat like poultry and fish is an excellent source of low fat protein. Have one good source of low fat protein with every meal.
Low fat dairy products these are a good source of protein and can be alternated with lean meats to provide your body with sufficient protein.
High fiber breakfast foods will aid digestion and so your breakfast should consist of foods made from whole wheat flour, wheat germ, oatmeal, or bran.
Obesity and a shapeless body are problems that plague many people around the world. Besides leading to an appearance that is less than ideal, it can also lead to severe health problems include heart failure, heart diseases, diabetes and more. While there are many ways to combat being overweight with the help of exercise and a proper diet and even medication, very severe causes of obesity can also be fixed with a surgical process known as Bariatric Surgery. So, here's everything you need to know about it.
- Affecting the Digestive Process: As per the normal digestive process, the food moves into the digestive tract, while its nutrients get collected with the help of a well functioning system that includes digestive juices and enzymes. This food moves through the digestive tract, passing through the oesophagus, before it goes down into the stomach where it meets the strong digestive acids, which break it down, and then it enters the small intestine. While the stomach can hold three pints of food at a time, there is a chance that some of this food may not get properly digested in the small intestine. In this case, the food enters the large intestine. Now, Bariatric Surgery helps in restricting the amount of food that a person can have and hold in the first place.
- The Process: This surgical procedure may be carried out by cutting open the stomach and removing a portion of the same. This procedure can also reroute the small intestine into the gastric pouch or the small stomach pouch. This process can also be done with laparoscopic invasion, where a few small incisions will be used to insert a tiny camera and instruments for the process.
- Ideal Candidates: If your BMI or body mass index is more than 40, then you can opt for this kind of surgery, as mere dieting and exercising will not help you in your weight loss endeavour. This surgery can also help in preventing the onset of type 2 diabetes mellitus. The patient also has to have reached the normal adult height in order to qualify for this surgery.
- Side Effects: After the surgery, the patient may experience a few side effects including leakages and bleeding. An incisional or an internal hernia may also occur after the surgery. Also, for patients who have a poor diet, there may be complications after the surgery due to less intake of necessary vitamins and minerals.
Once you undergo the surgery, it is important to commit to a proper diet with less food intake and proper exercise on a lifelong basis.

Living with a renal transplant constantly exposes you to the risk of organ rejection. Although it might sound scary, it usually happens because the medication needs to be tuned according to the requirements of your body. A change in medication usually solves the problem of a possible rejection, and a rejection becomes less likely if it doesn't happen within a year of the transplant. Some obvious signs of rejection are a pain on the region of transplant, fever, change in weight or low urine discharge.
The causes behind a renal rejection vary on the basis of the type of rejection that takes place. Here are three different types of renal rejection and their causes:
- Hyperacute Rejection - Hyperacute rejection occurs within 24 hours of the transplant. It can have an immediate effect and occurs as the existing antibodies act against the grafted material, causing irreversible destruction. The immune system may recognize it as a foreign body and destroy it. Hyperacute rejection is common for patients who have received multiple blood transfusions or have suffered from transplant rejection earlier. The tissue must be removed immediately before it becomes fatal for the recipient. This type of rejection can generally be avoided if the doctors type or match both the receiver and the organ donor. The organ is less likely to be rejected if there are similar antigens between donor and receiver.
- Acute Rejection - Acute rejection generally occurs after the first week of transplantation. Acute rejection is common in most recipients. Since a perfect match of antigens is rare to find, except in the case of identical twins, some amount acute rejection occurs in the case of all recipients. It can cause complications like bleeding and inflammation. The risk of acute rejection is highest in the first three months of the transplant.
- Chronic Rejection - Chronic rejection occurs months later after the transplantation. This happens over time when the immune system of the body reacts against the transplanted tissue and slowly damages the organ. In such a case, the kidneys can suffer from scarring or fibrosis and damaged blood vessels.

Whenever we choose to undergo a surgery, there are a lot of questions that we try to seek answers for. Here's a list of things one must know before he or she opts for kidney donation!
What is the rate of recovery?
The recovery period of the donor is usually in the range of 5-7 days. However, it depends on how fast an individual recovers and what is the kind of procedure performed on the patient. It can greatly vary from person to person. The donor might feel an itching sensation and experience pain as the incision heals. Activities such as contact sports and heavy lifting are not advised, post 6 weeks of surgery.
How does the transplant affect the donor?
Living with one kidney is not unusual and it is possible to lead a normal life with some to no problem at all. The donor’s kidney has a tendency to increase in size after the transplant. This happens to make up for the lost kidney. While some physical exercise is healthy for the body, activities that require heavy body movement should be avoided. Donors are required to go through extensive medical check every six months to avoid any possible complications.
Does donating a kidney affect life expectancy?
Life expectancy does not decrease after kidney donation and the chance of the existing kidney failure is limited too. Studies have revealed that a donor has a tendency of developing a high level of blood pressure. Having said this, a thorough discussion with the transplant team should be done to discuss any possible complications that might occur post the surgery.
Mental state after kidney donation:
A donor can go through a mixed set of emotions after donating a kidney. Overwhelming joy, depression, relief and anxiety are some of the common emotions a donor goes through. Studies have shown that less than 1% of all donors show any signs of regret. On the contrary, more than 80% donors reveal that they would have done the donation anyways. The donation experience is generally positive. If, however, a donor is going through emotions he cannot handle, he should join a self-help group or report to a doctor.
Is there any side effect of kidney donation?
Apart from the scar a patient receives after the surgery, there aren’t too many complications. Having said this, there are tendencies to develop high blood pressure, proteinuria and a reduced functionality of the kidney, resulting in pain. Long-term diseases such as nerve damage, obstruction, and hernia can catch up as well.
Is there any dietary restriction?
It is entirely possible to go back to your old and regular diet. However, in the case of any complications, a patient might have to skip few things from the diet. It is a good idea to get a clear picture about the dietary requirements from the kidney transplant team.
Does donation hinder in getting pregnant?
The medical advice from a doctor is that it is not a good idea to become pregnant till at least six weeks post the surgery. However, it is entirely possible to get pregnant after kidney donation. But it should be ensured that a patient receives very good prenatal care to reduce any possible complications. If you wish to discuss about any specific problem, you can consult a Nephrologist.
Obesity can make life miserable. From unhealthy eating habits to unhealthy lifestyles and medical conditions, obesity can be an amalgamation of many factors. Obese people are a greater risk of suffering from many serious health complications like type 2 diabetes, mood swings, and depression, cardiac problems, high blood pressure and high cholesterol, to name a few. It does not stop there. More alarming is the fact that obese people are an increased risk of suffering from different types of cancer.
Bariatric surgery comes as a saviour for highly obese people (with a BMI over 40), who have tried every possible treatment under the sun to lose weight without any success. Bariatric surgery has helped many severely obese people attain a healthy weight. Bariatric surgery can be of three types;
- Gastric bypass surgery (Roux-en-Y): This is one of the most common types of weight-loss surgery practised worldwide. The procedure involves rearranging (dividing) the stomach into a smaller upper pouch and a larger lower part. The smaller pouch is then connected to the small intestine. The food consumed will pass into the small intestine through the pouch. The idea is to rearrange the stomach in such a way that a person consumes a lesser quantity of food.
- Gastric banding (Laparoscopic Adjustable Gastric Band): In this procedure, the surgeon creates a small pouch at the upper part of the stomach by placing a band (lap band or A-band) around it. The pouch, true to its name, is used to hold the food consumed. The purpose of placing a band around the stomach (upper part) is to reduce the intake of food.
- Sleeve Gastrectomy (Gastric Sleeve surgery): In Sleeve Gastrectomy, surgeons remove a large portion of the stomach, leaving behind only a small sleeve-like pouch (hence the name). Like the other two surgeries, sleeve gastrectomy also aids in limiting the consumption of food.
- Duodenal switch: The fourth type of bariatric surgery, Duodenal switch with biliopancreatic diversion, is not very commonly used. Bariatric surgery has several health benefits. In addition to the weight loss, it plays a pivotal role in lowering the incidences of Type-2 Diabetes, depression, anxiety, coronary artery problems, sleep apnea cardiovascular diseases.
Research also suggest that bariatric surgery has been instrumental in reducing the chances of cancer (especially colon and breast cancer) by as much as 60%. The correlation between weight loss and reduced cancer instances is still a debatable topic. Some researchers and oncologists believe that the weight loss (bariatric surgery) brings about a hormonal modification which prevents the growth of tumour cells. Another study links obesity with an increased inflammation. In many cases, inflammation acts as a catalyst, accelerating the growth of cancer cells. Research is still going on to understand this correlation (obesity and reduced cancer rates) better.
Bariatric surgery has its share of risks and demerits. Consult your physician and get yourself thoroughly examined before opting for the surgery. If you wish to discuss any specific problem, you can consult a bariatrician.
